Not mechanic so i need some advise. 2 stroke outboard is acting as though it is not getting full fuel injected from tank. There are 2 line out of the tank w/ a primer pump. The primer pump works and motor starts and runs from a cold start. after boat runs and rests, even in the time it takes to get gas....the motor dies when throttled above idle. I've been giving it a quick full throttle and back when idling out of an area (safely of course) and that was hepling, but this week end i had to have a passenger pump the bulb in the line while i cranked and throttled until we got under way.
Ant help, or does anyone know a good outboard mechanic?
THANKS!

Not knowing what make and model your engine is, here is a wild guess! If your engine is managed by an ECU, the reason it does not quit when you advance the throttle quickly is because the throttle position sensor detects the rapid throttle advance, and sends a signal to the injectors to enrich the fuel system for a moment. Sorta like a "double pumper" carburator if you will. Depending on if your engine is EFI, it may be equipped with a vapor seperation tank (VST)for the high pressure end of the fuel system. This tank is a reservoir for fuel to be pumped out of, and unused fuel returned to so that it can cool and not be airated. If this VST system is not serviced, sometimes it will fail most times at WOT and at extended idle periods. Last, most units have small vacuum operated fuel pumps. If they are not working properly, and are in need of service they will not offer a steady diet of fuel to ANYTHING mentioned above, and nothing works as it should. I'll tell you this. If your engine is running lean (and it probably is because of your comment about pumping the bulb to make it run) it is very likely you will do some serious engine damage if you keep using the boat. If your engine is carburated, most of the above info is garbage.
